I'm really getting the hang of this equipment, and so far, I've done repairs to around a dozen boards, and it has always done the job. NO solder pads burnt off the boards, or any other damage. No blockages or malfunctions.
so far - I've got to say that I'm really pleased with this unit.
I hope to test it on a really fragile and difficult board like a Bally -32 MPU.
Really impressed thus far
